SAFE-LOCK.

SPECIFICATION forming part of Letters Patent No. 381.893, dated April 24, 1888.

Application filed December 8, 1886. Serial No. 22l,009. (No model.)

To @ZZ w/wm it may concern:

Be it known that I, JAMES WHITE, a citizen of the United States, residing at Cleveland, in

the county of Cuyahoga and State of Ohio, have 5 invented certain new and useful Improvements in Safe-Locks, of which the following is aspeciiication, reference being had therein to the accompanying drawings.

Figure l is a sectional view of a portion of a safe and of a lock. Fig. 2 is an elevation of the lock, the cover being removed and parts being broken away. Figs. 3, 4, 5, 6,and 7 show sonic of the details. Fig. 8 is a vertical section in the plane of the arbor. r 5 In some respects the improvements herein relate more particularly to locks of the character shown in my former patent, No. 293,388, of February '14, 1884, and reference may be made to that patent to understand details of construction which may be employed but which do not form the essential parts of the present invention.

In the drawings, A represents the outer plate, and B the inner plate, of a safe-wall. Between these there can be any desired number of supplemental plates or a iilling of any desired thickness.

The improvements herein shown and `de scribed can be applied to locking mechanisms 3o supported upon either the stationarywall of a safe or upon the vdoor,which may be regarded as a movable wall.

C represents generally the lock mounted in case C' and provided with one or more bolts, D. E indicates the arbor as a whole, it being for some purposes made intwo parts, ee. At

the outer end it is provided with a handle, F, and dial f, which may be of any usual or preferred construction.

G is a movable plate situated inside of the plate A, and H is a stationary plate arranged upon the inside of said movable plate G. The plate H is secured to the plate A by any suitable :fastening devices, it being so held rela- 45 tively thereto as to leave a chamber` or space within which the plate G can move to a lim- 'L Hited extent. At g there is a rivet-hinge,which supports one end ofthe plate G and allows it to turn. 5o At or near the otherend of the plate G there are formed two aperlures,one at g' and the other at g2 g3, the latter being bounded by two curved lines of different radii.

The arbor is provided with a cylindrical bearing part at e2 e3, between which it is re- 55 duced to a smaller diameter, forming a groove, as shown at J. rIhe part e2 is of the diameter of the part g2 of the apertures g2 g3 in plate G, and the part of the arbor at J is of the diameter of the smaller part, g3, of the said apertures 6o g2 g3. Hence the arbor, or a part thereof, can be passed longitudinally in through the aperture at g2, and then if the plate G be dropped, so that the part of the wall at g enters the` groove at J, it will be seen that the said plate 6 5 G will operate to lock the arbor against longitudinal movement.

To effect the raising and lowering of the plate G sufficiently for this purpose, (although said plate is so situated that thereis no access 7o to it directly, because of the filling or of the superposed metal plates,) I mount a shaft or spindle, S, on a line passing through the aperture g in plate G, the inner end of this shaft or spindle projecting through the inner plate, 75 B, of the door,andthe outer end being mounted in a bearingin therplate H, and having an eccentric, s, secured to said outer end, this eecentric lying in the plane of the plate G and being situated in the said aperture g. Said 8o aperture is of such shape that when the shaft or spindle S is rotated or rocked the eccentric srbears against the upper or lower wall of apA erture g and lifts or lowers the plate G.

When the arbor is to be inserted into posi 85 tion, a key is applied to shaft S, and it is turned sufficiently to cause eccentric s to lift plate G until aperture g2 registers with the arbor-holes in plates A and H. Then the arboris inserted until the groove J is in the 9o plane of plate G, whereupon the shaft S is turned so as to throw plate G down, bringing the wall at g3 into the groove at J, which .efa fects the locking of the arbor longitudinally, but can be rocked or rotated. 9 5

For some purposes it is desirable to be able to separate safe-arbors into two or more parts longitudinally in such way that while one part is allowed to remain in position relatively to the lock another can be withdrawn; and it roe is also desirable that when the parts are again joined they should, after being brought together, occupy exactly the same position relatively to each other that they had before separation, so that there shall be a guarantee that the combination which has been s et up with the tumblers can be still utilized and can be readily followed in opening the door, notwithstanding the separation of the parts of the arbor.

The arbor shown consists of two parts, c e, inner and outer, above mentioned. They are joined bya socket-piece or sleevecoupling, K, which consists ofa tube or socket-piece, having a socket of such shape that the ends of thc arborpieces must necessarily be introduced in one, and only one, way. The socket shown is in crosssection, of the form of a trapezoid, and the opposing ends of the arbor parts e c' are correspondingly shaped in section, so that the said ends can be inserted into the socket only when they are in one position relative to their direction of rotation. Sockets of other shapes will accomplish the same end; but I prefer one of about the character shown, as the metal can be easily worked into the required shapes and as it accomplishes the desired purpose.

The socket-piece K may bc attached to or formed with one of the parts of the arbor; but I prefer to make it separate and so arrange it that both of the other parts can be detached therefrom. The ends of the parts e e' are generally left separated, so as to prevent the arbor from conveying heat from the outer to the inkner side.

'Ihe inner end of the arbor is fitted to the lock, and is secured therein by means of a nut, N, screwed onto it. The nut O is employed for the purpose of adjusting the lock and all its parts and getting them in proper position before securing them to the safedoor.

The plate G is large enough to cover those parts of the lock which are ordinarily attacked and assists in preventing such attack from being successful. The arbor E and its plate G are made of steel and tempered drill-proof.

The safewalls vary somewhat in their depth or thickness, and therefore the employment of a socket-piece, like that at K, is advantageous, inasmuch as all of the arbors can be made of one size and yet be adapted to the differing doors.

The gearing and tumbler mechanism within the lock may be of any suitable character. As shown, the movement is conveyed by the arbor E and wheel U to wheel V, which is adapted by means of a pin to set in motion the camtumbler Vand the others of theseries mounted on the tumbler-shaft XV.

Above the tumblers and the arbor there is mounted the bolt D, it having an end, d, proA jecting through the case at one point and the end d projecting through the casing at another point, the two parts of the casing providing the bearings for the bolt. This bolt is recessed,

and in the recess is fitted the vertical swinging lever L, pivoted at Z to the bolt D, said lever carrying the fence s and the roller z above the cam-tumbler W and having the jaws at y adapted to engage with the pin t. This pin is carried by a sleeve, which is mounted on the arbor. When the tumblers are brought in proper position in relation to each other, the fence will drop into the recesses thereof, and the lever L can drop, so that the pin t shall engage with said lever, after which a further turning ofthe arbor can be made to slide the bolt D in one direction or the other. NVhen the lever L is up, and held there by the tumblers under the fence or by other device, the arbor cannot be utilized to slide the bolt. To prevent the bolt from being thrown back by jars or blows, I form upon the lever a dog, a, adapted to engage with an opposing part, b.

The bolt D, as above-described, extends entirel y across the lock-chamber, and is adapted to project at either end beyond the same, the opposite sides of the casing providing two bearings for it. I can use either end of the bolt, as circumstances may demand-that is to say, the device, as a whole, may be employed either as a right-hand or as a left-hand lock. I prefer to shape the bolt so that one end shall be somewhat lower than the other, whereby the bolt and its attachments can lie partly by the side of as well as above the arbor and tnmbler mechanism.

w is a stationary rib or guide so situated that when the lever L drops, a part thereof or part of the devices carried thereby-as, for instance, the fence s-can lie under this rib and engage upwardly with it, so that the lever cannot be raised while this engagement with the rib occurs; but the rib is short enough to permit the lever to rise either at one end of its throw or at the other, as occasion may demand.

The nut N serves as an abutment, bearing in one direction against a part of the lock, and the nutO is an abutment bearing in the opposite direction, the two together acting as fastenersone to prevent the arbor from moving outward relatively to the lock and the other preventing inward movement; and as one or both of these parts are adjustable the arbor can be readily kept exactly in proper position in relation to the other moving parts. The nut N is in the construction shown formed with a shoulder at n, which bears against a part of the lock casing or frame, ithaving also a prolonged thimble, as at n', to provide a suitable bearing. The nut O is shown as bearing against a short tubular extension of the lock casing or frame at c. \Vith these devices the inner part, e, of the arbor can be adjusted longitudinally, independently of the outer part or parts, the above-described arborlock at G acting upon the outer parts ofthe arbor independently of the inner.

I am aware of the fact that heretofore an arbor has been constructed in two parts, of

IOC

- tation shall be possible at all times.

which the outer could be Withdrawn; but in the one referred to thereware no means for locking the outer part of the arbor against longitudinal movement accessible only from the inner side of the safe-wall.

It will be seen that the line on which the arbor is divided is between the inner and the outer plates of the door, and that the arborlock which holds the outer end is also between the said plates, and that therefore said lock can be so aranged as to be accessible only from that side of the safe-wallon which is situated the `door-lock.

The arbor in my construction, considered as a whole, is, first, longitudinally extensible, and, secondly, is removable. By having it extensible the above-described adjustments in relation to thelock andthe other parts can be readily attained. The devices which fasten the inner end of the arbor are more or less independent of those which secure the outer part from longitudinal movement.

I am also aware of the fact that heretofore use has been madein locks for ordinary doors of acontinuous spindle extending through the door and provided on each side of the door with a knob in combination with a sliding plate on theinsicle ofthe door, which is adapted to engage with the arbor by means of a notch in such way as to prevent the arbor from sliding longitudinally and also from rotating. In

the present construction the arbor and arborlock are so constructed and related as that ro- The arbor-lock is arranged and related in a manner opposite to that followed in making the constructions last above referred to, in that itthe arbor-lock-engages with that part of the arbor adjacent to one side of the door, and is accessible from the opposite side of the door for actuating it.
